HIGH-VOLTAGE POWER ELECTRONIC BUILDING BLOCK DESIGN

摘要

The present disclosure relates to a Power Electronic Building Block (PEBB) 1 for a power converter. The PEBB comprises a semiconductor switch arrangement S comprising a plurality of semiconductor switches S1-S4, a capacitor arrangement C, and a busbar arrangement B, connecting the capacitor arrangement with the semiconductor switch arrangement. The busbar arrangement comprises a first laminated busbar B1 connecting a first plurality of capacitor elements C11-C14 of the capacitor arrangement to the semiconductor switch arrangement, and a second laminated busbar B2 connecting a second plurality of capacitor elements C21-C24 of the capacitor arrangement to the semiconductor switch arrangement. Each of the first and second laminated busbar comprises a positive conductor B1+ or B2+ laminated to a negative conductor B1- or B2-, each connected to each of the plurality of capacitor elements C11-C14 or C21-C24.
